Additionally, how long does postoperative atelectasis last? [8,18] The atelectasis can exceed 15–20%. The degree of atelectasis can be even more in obese patients. In the case of abdominal surgeries, the atelectasis can persist for several weeks postoperatively.
Also, how do you prevent atelectasis after surgery?
To help prevent atelectasis during and after surgery, your medical team may ask you to stop smoking and give you breathing exercises, medicines, or a breathing device such as a CPAP machine. Atelectasis may not cause signs or symptoms if it affects only a small area of lung.
